yBe it"knownthat' I, CHARLES F VAN HOOK, a citizen of the UnitedStates, and a resident of Paterson, in the county of Fass'aic' and State of New lJersey, havefinvented Acert-ain new and useul- Improve# ments in .Locking Devices. forl Spdols, of whichft'hefollowing a lspecixicatioln i' This invention relates to ylocking devices forspools, andthe object thereof is to provide adevicmof` the, Class specified simple in construction" and eiicient in'roperationy. *Othery [objects will' appear later'herein., l

My improvements, while adapted for use ina wide-rangefof machinery are, gforpun ,po'se'of illustration, 'shownas vapplied."to the locking of spools'in cradleswor `flyers of cordage or' wire machines,` In the drawings accompanying this specificationjmy improvements are shown in; their preferred embodiment,y and therein z" p d Figure 1 is a plan View of a wire lmachine cradle in which my improved' spool locking device .is incorporated.

Said lock pin when said crank is in the lpositionof Fig. 3, lengages hole 36 in side member 15 for holding bolts 18, 38 in retracted positions, respectively. For preventing said crank from accidentall withdrawal from the 'squared end of shaft 24 `when the bolts are withdrawn, ear 37 entending downwardly from the hub of said crank, is locked behind horn 39'projecting from the left hand end of side member 15. In kcase the machine should be started while crank 32 is in engav ement withr shaft 24`and locked in the position of Fig. 3,'with boltsr18, v38.v withdrawn, said crank handle lwill-l collide with Shaft 10y and'. stop the machine.V Or said crank-may be made suinciently'frail or may be weakened as at 40, so that, 'l immediately 4following the commencementof rotationof,v cradle 2, handle 3`4vwillcol'li'de with shaft 10 and said crank broken in two, therebyreleas'ing bolts 18, 38, which ythereupon are forced their springsto`r engage trunnions 12, 13 and hold there in their bearings, respectively. Spool 11"will thusbe prevented from moving out of thecladle.

While in most cases the bolt springs are eiiicient for holding the bolts in their inner positions for retaining the spool trunnions in theirbearings, added means of security are provided in locking pin 42 for rock sleeve 27. Saidlocking'pin ismounted asuitable bearing 46 inthe left hand end of cradle 2 and is spring impelled to engagement'with hole 44 in the under side of said rock'sleev'e. V'Pin 42 may be retracted by grasping'its head 45. ""In the modification of Fig. 8, the undercutfportionk ofthe trunnion bearing has been omitted an'dffthe engaging end of bolt 18 lprdi'fided-with an -over'hai'iging lip 18t1 for retaining said trunnion in its bearing. 'Ihis permits"a"m`ore facile withdrawal of the spool from thecradle, butin most cases the formof Figf7 isi preferred. y

The/operation of the device will be readily understood y frmv the foregoing description. Siiiiice ituto stateu'that Awhencrank 32 is raisedfromthe position of Fig. 2 tof that of Eig. 3 andpin 35 entered in hole 36, bolts 18,38 are thereby withdrawn and spool 11 may befreely removedand replaced in its bearings. i Then, by kwithdrawing pin 35 from hole 36 andl permitting crank 32 to swing downwardly under the urge of the bolt springs to the position of Fig. 2, ear 3K7 is swung `from'behind horn 39` and said crank may be'withdrawn from the squared end Vof. shaft 24. In the meantime lock pin 42. has entered hole 44 in sleeve 27, thereby locking said sleeve against rotation and bolts 18, 38k in their operative positions, see bolt 18 Fig-7. In case crank 32 should be left the position of Fig. 3 and the machine 'started,handle Y34 will strike shaft 10 ed on 'said bearing member, an arm upstanding on said sleeve, a bolt pivotally connected at one end thereof with said arm, the other end of said bolt being adapted for entering said bearing, means for urging said 'bolt toward saidy bearing, and hand operated means for withdrawing said bolt.

2.

5. In a device of the` character specified the combination of a member having opposite trunnions, a member having Vpocket bearings with undercut portions respectively for said trunnions, a sprinfr urged reciprocating bolt for releasably lholding each of said trunnions in its bearing, supplemental locking means for said bolts, means for releasing said locking means and meansA for simultaneously withdrawing said bolts.'

8. In a device of the character specified the combination of a member having opposite trunnions, a cradle having opposite side members, each of said members having. a pocket bearing for the yreception of one of said trunnions, a rock sleeve pivotally mounted on said cradle, opposite upstanding arms on said rock sleeve, opposite bolts mounted for reciprocation in opposite sides respectively of said cradle, said bolts being pivotally connected at one end with said arms respectively, the other ends of said bolts respectively being adapted for entering said bearings, means for urging said bolts toward said bearings, means for rocking said rock sleeve, and means for locking said sleeve for holding said bolts in their inner posit-ions respectively.
